Global statistics display how many messages were successfully delivered, how many messages were blocked and why.
Messages are classified as:
OK |
the message was delivered correctly. |
DNSBL |
the session was refused due to a "DNS Black List" filter. The sender's IP address has been banned due to spamming or other unwanted activities. |
ANA |
the message was refused because the sender has no access permission (Access Not Allowed). |
AS |
the message was refused by the Anti-Spam. |
AV |
the message was detected by the Anti-Virus. |
DBF |
the message was "Deleted By Filter". This is usually a Content Filter. |
SDME |
the message was refused because the sender's domain doesn't exist (Sender's Domain Must Exist). |
SCAN |
an incoming connection has been established but no message delivery was attempted. This behaviour is typical of port and service scan tools. |
TARP |
the originating IP address was tarpitted by IceWarp Server, thus the delivery session was rejected. Tarpitting is now Intrusion Prevention. |
WDNR |
the message was refused because relaying to the final recipient was not allowed (We Do Not Relay). |
UNK |
the message was refused because the recipient address doesn't exist (User Unknown). |
CNC |
a client session failed because IceWarp Server couldn't connect to the remote SMTP server (Could Not Connect). |
ERROR |
the message wasn't delivered due to some unspecified error. |
CA |
the message was accepted and forwarded to a catch-all address (Catch All account). |
INCPLT |
the session is incomplete. |
GRLST |
the message was refused by Gray Listing. |
The table reports the number of sessions or messages succeeded and those refused for each reason.
You can obtain a report per hour, day, week or month selecting the "Group by" selector.
Using Common filters you can focus on a part of the entire data that was logged.
After the report has been generated, you can easily focus your attention on relevant situations using the highlight threshold option. Values higher than the threshold compared to the total "Processed" are highlighted.
The following picture shows how SCAN and UNK activities are relevant on the server being analyzed.
Using the percentage button "%", you can switch values so they are specified in percentage in relation to the processed messages value. This is useful to estimate the importance of each value/item.
